In general The machine to which the present invention is shown appliedin its preferred form, includes a plurality of totalizers, one foraccumulating each classification of transactions and one foraccumulating each individual transaction. These totalizers are operatedby differential mechanism under control of de pressible keys. Thedifferential mechanism provides means for adjusting type elements (notshown) to print on the issuing receipt the amounts entered in thetotalizers, together with the total of the same, and also to print onthe record strip, which is retained in the machine, transaction andclassification totals.

Printing and indicating mechanisms are present invention, they areneither shown or described herein.

The machine is provided with a plurality of clerks keys and specialcounters therefor (not shown), to set up type and control the 5 nesswhere it is desired to issue an itemized printed receipt to the customerand reta n in the machine a record strip containing not only the totalsof each itemized receipt issued, but also the amounts of eachsingle-item transaction.

Operating mechanism The machine is manually operated by a handle 50(Fig. 1), mounted on a stud 51. Connected to the handle 50 is a pinion52 meshing with a gear 53 mounted on a stud 54 projecting from the frameof the machine. The gear 53 meshes with a gear 55 secured on the maindrive shaft 56. The ratio of the pinion 52 and the gear 55 is such thattwo rotations of the handle will cause one rotation of a main driveshaft 56.

The machine may also be operated by an electric motor. Only a part ofthe motor clutch mechanism is shown in the accompanying drawings. Themotor is mounted on the left hand side frame of the machine. The clutchmechanism between the motor and the machine includes a spring actuateddisk 57 (Fig. 10) mounted upon a stud 58. This disk carries a. lug 59,which normally contacts the forward end 60 of an arm 61 pivoted on astud 62 on the frame of the, machine. An arm 63 secured to the arm 61carries a pin 64 which normally rests on the curved edge 65 of an arm 66pivoted on a printer drive shaft 67 'ournaled in the printer frame. Thearm 66 is connected by alink 68 to an arm 69 secured to a shaft 70extending across the entire machine and journaled in the frames thereof.'hen the shaft 70 is rocked clockwise to relcase the machine, as willhereinafter be described, the arm 66 is rocked clockwise from beneaththe pin 64, permitting the spring 75, attached to the arm 63 and to apin 76 projecting from the frame of the machine, to move the end 60 ofthe arm '61 away from the lug 59. The clockwisemovement of the lever islimited by a pin 77 projecting from the frame of the machine. Uponrelease of the arm 61 the disk 57 is moved clockwise bv a spring (notshown), effecting an operative connection between the motor and thedriving clutch to operate the machine.

The main drive shaft 56 is driven from a gear 78 secured to one of thedriving clutch members (not shown). This gear meshes with a gear 79freely mounted on a stud 80 supported in the side frame of the machine.Pinned to the gear 79 is a gear 81 which meshes with a gear 82 securedto the ma n drive shaft 56. The gear 81 also meshes with a gear 83secured to the printer drive shaft 67. The main drive shaft 56 and theprinter drive shaft 67 are given one complete rotation during an addingoperation of the machine. The arm 61 is restorcd to its locking positionnear the end of the o eration of the machine by means of a disk 84 Fig.9) pinned to the shaft 67. This disk carries a pin 85, which engages acurved edge 86 of the arm 63 to restore the arm 61 to stop the machine.This permits the return of the arm 66 and consequently the shaft 70 totheir normal positions. Keg board The keyboard comprises one bank ofclerks keys 96, a bank of transaction keys 30 and 32 (Fig. 4), astarting bar 33 (Fig. 1), a total lever 34 (Fig. 7) for controlling themachine for total and sub-total operations, and a plurality of banks ofamount keys (not shown). A key 31 located in the transaction bank isprovided to manually release any of the keys in this bank.

The banks of amount keys are not shown or described herein as they formno part of the present invention. Reference for a description of thesame can be made to the copending application referred to, of which thisis a division.

The machine is normally released for operation by depression of a clerkskey 96 (Fig. 6), a transaction key 30 or 32 (Fig. 4), and the startingbar 33 (Fig. 1), which releases the shaft 70.

The starting bar 33 is detachably mounted upon a slide 100, supported bytwo studs 101 engaging elongated openings 102 in the slide 100. Thesestuds are mounted on the frame of the machine. The bar is retained inits normal outer position by a spring 103. The slide carries a pin 104embraced by a forked arm 105 pivoted on the stud 51 and connected by alink 106 to one arm of a bell crank lever 107 pivoted on a rod 108supported in the frame of the machine. The other arm 109 of the leverlies in the path of a half-round stud 110, carried by arm 111 pinned tothe shaft 70, to compel depression of the bar 33 to release the machine.Depression of the starting bar moves the arm 109 out of the path of thestud 110, thereby permitting the shaft to be rocked to release theclutch mechanism previously described.

When the shaft 70 is rocked to release the motor clutch, the stud movesunder the arm 109, thus holding the starting bar 33 depressed. Near theend of the operation of the machine, the shaft 70 moves back to, andpast its home position, and, consequently the stud 110 moves out fromunder the arm 109 and past the end of a non-repeat awl 118 pivoted onthe rod 108. Removal of the stud 110 from beneath the arm 109 permitsthe spring 103 to return the starting bar 33 to its normal releasedposition.

The non-repeat pawl 118 is provided to prevent repeat operations it thestarting bar should be held depressed during the entire operation ofthemachine. This pawl is normally held against an off-set portion of thearm 109 by a spring (not shown), but when thestarting bar 33 isdepressed, the arm 109 is elevated out of contact with the non-repeatpawl 118. and the stud 110 prevents the pawl from following the arm 109.If the starting bar 33 is held depressed during the entire operation ofthe machine, thus holding the arm 109 elevated, then near the end of theoperation of the machine, when the shaft 70, arm 111 and stud 110 aremoved back past their home positons and past the end of the non-repeatpawl 118, the spring (not shown) connected to the pawl and a pin on themachine frame, will rock the pawl counterclockwise until it contacts theelevated arm 109, thus locking the machine against another operation. Inthis position, the end of the non-repeat pawl 118 is in the path of thestud 110, consequently the machine cannot be releascd. even though thestarting bar 33 is held depressed and the arm 109 remains elevated. lhen pressure is removed from the bar 33 the spring 103 restores the bar33 and the arm 109 to normal position, and the non-repeat pawl 118 isreturned to normal position by the arm 109.

The shaft 79 is moved by an arm 121 secured to the shaft outside of theright end frame of the machine. This arm carries a screw stud 122supporting the spring retaining pilots 123, placed on the opposlte sidesof a link 124, slotted at 126 to move over the stud. A coiled spring 125surrounding the lower ends of the pilots 123, is compressed between theshoulders on said pilots the lower end of the slot 126 in the link 124.From this it can be seen that, as the starting bar is depressed and thearm 109'is moved counter-clockwise, the spring 125 is released to rockthe shaft 70 clockwise to release the motor clutch mechanism previouslydescribed.

Transaction keys The transaction keys are divided into two groupsarranged in a single bank and mounted in a common frame 129 (Fig. 4)supported by rods 93. The keys 30 of the upper group are used inregistering multiple-item transactions. The keys 32 of the lower groupare used in registering single-item transactions.

The keys are held in their normal positions by springs not shown and areretained in depressed positions by a spring urged locking detent 131engaging pins 130 on the keys. The detent 131 is mounted on arms 132 andThe key pins 130 also wipe against beveled edges 128 and 143 of recessesformed in a settingbar 136 (Figs. 2, 3 and to'shift the 3 bar andoperate interlocking mechanism between the transaction keys and thestarting bar 33. The settin bar 136 is supported by arms 137 and 138.Mounted in the arm 137 is a pin 139, which engages an upwardly extendingarm 140 of a yoke 141, pivoted on the rod 108. As a transaction key isdepressed, the pin 130 will engage the inclined edge 128 or 143 (Figs. 3and 5) on the setting bar 136 and move the detent bar toward the left torock the yoke 141 counter-clockwise. The arm 140 is maintained inengagement with the pin 139 by a spring 144. As the yoke 141 movescounter-clockwise, it carries with it a retaining arm 145 pivoted on therod 108 and held in contact with the upper edge of the yoke 141 by aspring 146. This retaining arm has a pro ection 147 whichnormally liesin the path of a flattened stud 148 mounted in an arm 149 pinned to theshaft 70. An interlock is thereby formed between the transaction keysand the starting bar 33 so that if the starting bar is operated withoutdepressing a transaction key, the machine will not be released foroperation. If the transaction key is depressed in its proper sequence,the projection 147 will be out of the path of the stud 148 when thestarting bar is operated.

The transaction keys are not restored to normal positions during theoperation of the machine, as are the amount keys, and in some cases, theclerks keys, but remain in depressed positions until released bydepression of another transaction key, or the release key 31 (Fig. 4).This release key has a pin 159, normally adjacent the angle side of aprojection 160 on the detent 131 to move this detent to the left torelease any depressed transaction key. Depression of the release keydoes not affect the setting bar 136, as this bar has a recess oppositethe pin 159 as shown in Fig. 3.

In entering a multiple item transaction, the operated key should belocked in depressed position, and all other transaction keys lockedagainst depression, until the completion of the entire transaction.

This result may be conveniently obtained by arranging the inclined wallsof those recesses in the setting bar 136 which lie beneath the multipleitem keys 30, so that upon depression of a multiple item key 30, thesetting bar 136 is given a greater extent of movement than is impartedto it by the single item key 32, and by providing the arm 138, to whichthe lower end of the setting bar 136 is pivoted, with a notch 154 (Figs.2 and 3) engageable by a locking bail 153 journaled on a shaft 152.

When a single item key 32 is depressed, the setting bar 136 is notshifted a suilicient distance to swing the notched arm 138 far enough tobring the notch 154 into the path of the locking bail 153. But, owing tothe longer incline of the edges 143 of the recesses in the setting bar136 beneath the multiple key will shift the setting item keys 30,depression of a multiple item bar 136 and its arm 138 to such an extentthat, upon complete depression of the key and the restoration of thedetent- 131 and its arm 133 to locking position, the notch 154 in thearm'138 is located in the path of the locking bail 153, preparatory tothe entry of the edge of the locking bail 153 thereinto.

An arm 151, pivoted on the shaft 152, is secured to the lock hail 153 tocontrol the latter. The inner free end of the bail arm 151 extendsinwardly into the path of a stud 155 projecting from the usualdifferentially mov' able arm 275, which normally maintains the bail arm151 and the locking bail 153 in idle position against the tension of aspring connected with the arm 151, which tends to rock the arm 151 andlocking bail 153 counterclockwise toward the arm 138.

On a multiple item operation, a multiple item key, and the amount keysare depressed,

and an operation of the machine rocks the differential arm 275clockwise, in a well known manner, to select the proper totalizer, andin so doing, the differential arm 275 releases the bail arm 151 to theaction of a spring, which rocks the arm 151 and its looking bail 153counter-clockwise, to enter the bail 153 in the notch 154 andhold thedepressed multiple item key 30 in its depressed position (as shown inFig. 3), throughout two or more operations of the machine.

The extended travel permitted the look ing bail 153 when it enters thenotch 154,

positions the bail beneath the arm 133 to thereby look all other keys inthe transaction bank against depression.

- When a single item key 32 is depressed, and the machine is operated,the limited travel permitted the locking bail 153 is such that the freeend of the bail arm 151 remains in the path of the stud 155, when thebail contacts the unnotched end of the arm 138 (as shown in Fig. 2), sothat upon the return of the differential arm 275, at the end of theoperation, the stud contacts the. bail arm 151 and restores it, togetherwith the bail 153, to idle position (as shown in Fin. 4). But. when amultiple item key 30 is depressed, and the machine is operated, theextent. of travel of the bail 153 withdraws the free end of the arm 151from the path of the stud 155 on the differential arm 275 (Fig. 3) asabove described.

Therefore, to effect the release of the depressed multiple item key 30,and the restoration of the locking bail 153 to its idle position, theusual total lever 34 (Fig. 7) is provided with a cam slot 190. After allthe items of a multiple item transaction have been entered in themachine, the total lever 34 is manually shifted from its normal addposition to the item total position,

and after the total is printed, the total lever is restored to itsnormal add position. A roller 189 carried on one arm of the intermediatelever 191, pivoted at 192, enters the cam slot 190 in the total lever.The opposite arm 193 of the lever 19]. has formed on one edge thereof acam recess 187. A link 194, also pivoted at 192, and overlying the arm193 of the lever 191, has a complementary cam recess 188 formed in itsedge, which coop crates with the cam recess formed in the arm 193 of thelever 191 to constitute a cam sl t. A spring 199 connects a stud 198 onthe link 194 with the arm 193 of the lever 191 to hold these partstogether, with the stud 19 in con tact with the upper end of the arm193. This arrangement provides a flexible cam mecha nism which willyield to prevent injury to the machine in case the shaft 152 is lockedby a depressed key, at the time the total lever 34 is shifted from itsadd position. A crank 190 fast on the shaft 152, on which the bailcarrying arm 151 is pivoted, carries a roller 195 entered in the camslot formed by the complementary edges 187 and 188 of the arm 193 andthe link 194 respectively.

When the total lever 34 is adjusted from its add position to its itemtotal position, its cam slot 190 rocks the lever 191 in acounter-clockwise direction, and the arm 193 of the lever 191 togetherwith the link 194, rocks the crank 196 and the shaft 152 in a clockwisedirection.

A tappet 150 (Fig. 4), fast on the shaft 152, is thereby rocked tocontact a stud on the bail arm 151.

As is customary in machines of the type to which this invention isapplied, a total taking operation includes two cycles of rotation of themain drive shaft 56 of the machine, during the latter part of the firstof which cycles, the shaft 152 is rotated slightlv farther in aclockwise direction (by means later described) which presses the tappet150 against the stud on the bail arm 151 to rock the bail arm 151clockwise sufiiciently to return the free end of the bail arm into thepath of the stud 155 on the differential arm 275, when the latter is ata point some distance above the bail arm 151, so that as thedifferential arm 275 is restored, its stud strikes the free end of thebail arm 151 and withdraws the locking bail 158 from the notch 154 inthe arm 138 to permit the release of the depressed multiple item key 30.

Near the end of the operation of the ma chine, the parts operated by thedepression of the starting bar 33 are restored to their normal positionsby a cam 200 (Fig. 1) formed in the side of the gear Cooperating withthis cam is a roller 201 on an arm 202 pivotally mounted on a stud 203projecting from the side frame. The upper end of the arm 202 carries apin 204 which normally engages aslot 205 formed in the link 124.

As the gear 53 rotates, the arm is moved first clockwise and thencounter-clockwise, which causes the link 124 to move downwardly and thenreturn. During the operation of the machine, the headed stud 122 is incontact with the upper end of the slot 126, and the shaft is rockedcounter-clockwise, which permits the arm 109 (Fig. 1) and the retainingarm 145 (Fig. 4) to return to their normal positions, at the same timeallowing all of the parts cooperating therewith to return to theirnormal positions.

Clerks keys Four clerks keys 96 (Fig. 6) are provided. These keys arelocated near the left hand side of the machine and are mounted in a keyframe 95 supported by the rod 93 and a rod 94. The keys 96 whendepressed are so retained by a detent 164 which is moved toward theright when one of the keys is depressed. The detent- 164 is spring urgedtoward the left and after the key has been depressed, the shoulder 165engages a pin 97 mounted in the shank of the key. The detent is slidablymounted on headed studs 166. The depressed clerks key is returned tonormal by a spring (not shown) near the end of a single-item operationand near the end of the second cycle of a total-taking operation. Thedetent 164 is moved to release the keys by a bell crank, one arm 168 ofwhich constitutes a cam adapted to engage a pin 169 on the detent 164 tomove the latter to release any depressed clerks key. The bell crank ispivoted on a stud 170 and is held in its normal position by a spring171. The other arm 172 of the bell crank is adapted to be engaged by apin 173 carried on a segment gear 17 4 pivoted upon the sleeve 163. Asthe segment gear moves clockwise, the pin 173 strikes the arm 172 andmoves it in a counter-clockwise direction. As the pin 173 passes off thearm, the bell crank will be returned to its normal position by thespring 171. When the segment gear 174 is moved counter-clockwise to itsnormal position, the pin 173 will strike the rear side of the arm 172 ofthe bell crank, thereby rocking the cam arm 168 clockwise to engage thepin 169, thus moving the detent 164 to the right. This movement of thedetent disengages the shoulder 165 from the pin 97, permitting thedepressed key to be returned to its normal position. When the pin 173passes off the arm 172, the spring 171 again returns said arm to itsnormal position.

Mechanism is provided to compel the depression of a clerks key beforethe machine can be released for operation. Pinned to the shaft 70 is anarm 180 (Fig. 6) normally contacting the under side of a pin 181 carriedby a releasing slide 182 slidably mounted on screw studs 166 andretained in its nor mal position by a spring 183. As a clerks key isdepressed, the pin 97 will engage an inclined edge 184 of the releasingslide 182 and move the slide toward the left to remove the pin 181 fromthe arm 180. The shaft 70 is then free to be rockcd, as hereinbcforedescribed, to release the machine for operation.

The segment 17 4 has a rearwardly extending arm 210 (Figs. 6 and 7),connected by a link 211 (Fig. 8) to a lever 212 pivoted on the stud 213projecting from the printer frame (not shown). The lever 212 has adownwardly extending arm 214 to which is attached a spring 215. Thisspring is normally under tension, and when released by movement of alink 220 to the right (Fig. 10) will, through the lever 212 and link211, impart to the gear segment 174 its clockwise movement. Theclockwise movement of the lever 212 and consequently the clockwisemovement of the segment 17 4 is limited by a stud 216 in the path of anarm 217 on the lever 212.

The counter-clockwise movement of the segment 174 is accomplished asfollows: The link 220, (Fig. 10) near its left hand end, is guided by apin 221 projecting from the printer frame 209. At its right hand end thelink 220 is pivoted to a lever 222. This lever is pivoted on a stud 223and is given a movement first clockwise and then counterclockwise by apair of cams 224, (Fig. 11), secured to the shaft 67 and cooperatingwith rollers 226, carried by the lever 222. The forward end of the link220 engages the pin 173 on the segment 174 to normally maintain thesegment 17 4 in position, and when the link 220 moves to the right, thesegment 17 4 is released to the action of its spring 215. The end of thelink 220 also controls the stud 173 to return the segment 174 to itsnormal position upon return movement of the link 220 toward the left.

The. gear teeth on the segment 17 4 are not used in the presentinvention, but it is though that a brief description of their use, asillustrated and described in the above mentioned co-pending application,will be helpful. This segment is adapted to receive a long and a shortoscillation to impart to the issuing receipt a long feed and a shortfeed. The length of the feed is governed by the character of thetransaction. The movement of the feeding mechanism on 'a single-itemtransaction is equal to the greater movement of the segment 17 4. Whenan item of a multiple-item transaction is entered, the feeding mechanismwill move a distance equal to the shorter movement of the segment 174.

It is therefore to be understood that when an individual item of amultiple-item transaction is entered in the machine, it is not desiredthat the clerks key should be released.

A description of the mechanism for controlling the release of the clerkskey will now be given.

Pivoted on a shaft 230 is an arm 231 (Figs.

8, 10, 12 and 13) which is operated by a flexible drive mechanism onaccount of the overlapping of time in the operation of the segment 174and the arm 231. Projecting laterally from-the arm 231 is a pin 232rojectin between two arms 233 and 234 ig. 8) held in contact with thepin b aspring 235 stretched between the arms. hese arms are driven by apin 236 carried by a lever 237, pinned to the shaft 230. When the arm231 IS moved counter-clockwise to the position shown in Fig. 12, thehook ortion of the arm will be in the path of a attened stud 238,carried by the segement 174. With the arm 231 in this position, thesegment 174 will be limited to its shorter movement. The arm 231 isplaced in this position by mechanism controlled from the transactionkeys. Secured to the segment lever 240 (Fig. 10) is a cam arm 241 (Figs.12 and 13) the outer edge 245 of which contacts a roller 242 carried byan arm 243 loose on the shaft 230 (Figs. 10, 12 and 13) This cam arm 241has an inn-er edge 244 in addition to its outer edge 245. n single-itemtransactions the outer edge 245 of the cam arm is in contact with theroller 242, with the arm 231 in its ineffective position in relation tothe flattened stud 238. With the arm 231 in this position, the depressedclerks key will be released on each single'item transaction operation.In a multiple-item transaction operation the cam arm 241 is given acounterclockwise movement, sufiicient to bring the inner edge 244 of thecam arm 241 opposite the roller, whereupon a spring 246, stretchedbetween an arm 247 pinned to the shaft 230 and a pin projecting from theprinter frame, will rock the arm 231 counter-clockwise into the path ofthe flattened stud 238. In this position the arm 231 will limit theclockwise movement of the segment 174. This limited movement of thesegment is not sufiicient to carry the pin 173 past the arm 172, forwhich reason the cam arm 168 will not receive a clockwise movement, andthe clerks key will not be released when the items of a multipleitemtransaction are entered.

After the last item of a multiple-item transaction has been entered, thetotalizing lever 34 (Fig. 7) is moved to the item total position, whichlmparts an initial movement to the shaft 152 scribed.

In machines of the type to which the present invention is shown applied,two cycles of operation are performed by the machine when taking totals.During a multiple-item total taking operation, the cam arm 241 remainsin the position to which it is moved during the multiple-item entryoperation. However, when the total lever 34 is shifted to the itemtotalposition the arm 231 is shifted to the position shown in Fig. 13. Duringthe first cycle the cams 224 (Fig. 11) rock the lever 222 cam arm 168 isnot moved, and

(Figs. 12 and 13) as previously declockwise which moves the link 220 tothe right, as previously stated, whereupon the s ring 215 (Fig. 8) rocksthe segment 174 c ockwise. Near the end of such first cycle of operationthe link 220 is returned to normal and moves the segment 174 to itsnormal position to feed the receipt :1 short distance to space the totalfrom the last printed item, as is fully disclosed in the parentapplication above mentioned. But, as the pin 173 did not pass to theright of the arm 172, due to the short movement of the segment 174, thethe clerks key remains depressed at the end of the first cycle of 0ration of an item-total operation. The mecli nism which shifts the arm231 to the position shown in Fig. 13 is as follows:

Secured to the shaft 152 is an arm 250 (Figs. 10, 12 and 13) connectedto one end of a pitman 251, which at its opposite end is bi urcated toslide on the shaft 230. The pitman 251 carries a roller 252, whichengages an arm 253 pinned to the shaft 230. The ini tial, clockwisemovement of the shaft 152 will, through the means just described, rockthe arm 253, shaft 230 and arm 231 clockwise to the position shown inFig. 13, thus leaving the 00k arm 231 above the stud 238 so that thesegment 174 is limited to a short movement, and consequently, thedepressed clerks key will not be released during the first cycle, asabove mentioned.

Near the end of the first cycle of operation the shaft 152 is given anadditional movement, hereinafter described, to move the pitman 251farther toward the right (Fig. 10), and in so doing the roller 252 earnsthe arm 253 farther clockwise to move the hook of the arm 231 out of thepath of the stud 238, to permit the segment 174 to receive its fullextent of movement under the influence of the spring 215, during thesecond cycle of the operation. During such second cycle, and before thesegment 174 can be moved its full extent as just stated, the cams 224move the link 220 to the right to permit the spring 215 to function asabove stated. Now, this full extent of movement of the segment 174 movesthe stud 173 to the right of the bell crank arm 172, so that when thesegment 174 is returned to its normal position by the link 220, the bellcrank 172 is rocked by the stud 173, whereupon the cam arm 168, by itscontact with the Stud 169 (Fig. 6), cams the detent 164 to the ri ht torelease the depressed clerks key.

when taking totals from classification totalizers, other than themultiple-item totalizers, one of the single-item keys is depressed toselect a totalizer, and therefore, the cam arm 241, under control wouldbe shifted to such a position as to move the outer edge 245 of the camarm beneath the roller 242, (Fig. 10), which would move the arm 231 outof the path of the stud 238, and then the segment 174 would receive twofull of a single-item key,

extents of movement, one during each cycle of operation, which wouldresult in the receipt getting two'long feeds, and the clerks key wouldbe released during the first cycle of such a total taking operation. I

To avoid such a release of the clerks key, during the first cycle, amechanism to move the roller 242 out of the path of the outer edge 245of the cam arm 241 before such total taking operation, without movingthe arm 231, is provided, and is controlled by the manual movement ofthe total lever 34.

As above mentioned, the shaft 152 is given an initial movement when thetotal lever is shifted to any total taking position, but as the initialmovement of the shaft 152 is not sufficient to move the roller 242 outof the path of the outer edge 245 of the cam arm 241, an arm 254 ispinned to the shaft 152 and connected to one end of the link 255 which,at its opposite end, carries a roller 256 engaging a slot 257 in the arm243 loose on the shaft 230, and a slot 258 in the arm 247 pinned to theshaft 230. As the shaft 152 is given its initial movement, the roller256 moves downwardly in the slots 257 and 258 (Fig. 10), causing the arm243 to move clockwise to a position in which the roller 242 is clear ofthe cam arm 241 (Fig. 13). When the shaft 152 receives an additionalmovement, hereinafter to be described, the roller 256 continues itsdownward movement in the slots 257 and 258 without imparting additionalmovement to the arms 243 and 247, the lower part of the slots beingparallel each with the other. This additional movement of the shaft 152imparts additional movement to the arm 253, which gives additionalclockwise movement to the hooked arm 231 placing it in its ineffectiveposition in the same manner as described for a multiple-item totaltaking operation. With the hooked arm 231 in its ineffective position,the segment 174 will be permitted its full extent of movement during thesecond cycle of a total-taking operation, which will position the pin173 to the right of arm 172 of the bell crank. When the segment 174 isreturned to its normal position, the cam arm 168 will move the detent164 to release the depressed clerks key.

The mechanism for giving the shaft 152 its additional movement, ontotal-taking operations, will now be described.

Cooperating with a roller 260 carried by a pitman 261 is a cam 262 (Fig.1). Connected to the lower end of the pitman is a lever 263 pivoted on astud 203 and connected at its opposite ends, by the link 264, to an arm265 secured to the shaft 152. The cam 262 is freely mounted on the stud54, and, is normally retained in its in operative position by the roller260 being in a notch 266, formed in the cam. When the shaft 152receives'its initial movement, by the total lever 34, as previouslydescribed, the roller 260 is withdrawn from the notch 266 into thegroove of the cam 262. At the same time a coupling plate 269 is shiftedto lock the cam 2.62 to the gear 263, in a well known manner wherebythey will be made to rotate in unison. The cam 262, through the pitman261, lever 263, link 264 and arm 265, now rocks the shaft 152 far enoughto move the roller 256 (Fig. 12) to operate the arms 243 and 247 in themanner, and for the purpose above described, and

also to move the pitman 251 to perform the function stated. The movementof the pitman 261, through the stud 267, cooperating with the slot 268,will cause the link 124 to move clockwise, thereby placing the pin 204in an ineffective position in the opening 205 so that the shaft will notbe returned to its normal position until the second cycle of operation,all of which is old in the art.

Differential mechanism Differential mechanism such as that fully shownand described in the parent case, is provided to operate the totalizersdifferentially, and to select them for operation, also to set uptype-carriers in the printer, controlled by the amount and transactionkeys.

Briefly stated, such an amount differential comprises a driving segmenthaving an invariable movement, differentially movable racks foractuating the totalizer wheels and a latch mechanism, which serves toconnect the differentially movable actuating rack with the invariablemovable driving segment. The differential mechanism which cooperateswith the amount banks is similar to that used with the transactionbanks, hereinafter to be described, except that a differentially movablemember, carrying three actuator racks or segments, which cooperate withthe three lines of totalizer wheels, is used instead of the arm 275.

It is not thought necessary to describe in detail the differentialmechanism associated with the banks of amount keys as this structure isold and well known in the art, and forms no part of this invention.Reference may be had to theabove mentioned Shipley application for acomplete disclosure thereof.-

Transaction differential v 274 which likewise is rocked clockwise andback toits normal position. The arm 275 is normally connected to thesegment 274 by means of a latch 276. The arm 275 is given a clockwisemovement until it is disconnected i from the segment 274 by a depressedkey. As

the segment 274 moves counter-clockwise to its normal position the arm275 is again connected thereto and returned to its normal position, allof which is old and well known in the art.

Associated with the differential mechanism is a beam 277 which at itsright hand end is bifurcated to cooperate with a pin 278 in a link 279.The link 279 at its lower end is connected to an arm 280 secured to oneend of a sleeve 281 (Fig. 10) on a rod 282.

The movement of the arm 280 also selects the classification totalizersinto which the amount set up on the amount keys is to be added. Thisselection is effected through segment gear 283 secured to arm 280, rack284, slide 285, cam lates (not shown) secured to the slide amcooperating with projections on totalizer frames 286 and 287 on whichthe transaction totalizers are mounted. The upper totalizer frame 288carries agrand totalizer which is not under control of the transactionkeys. As this totalizer selection is nota part of the invention claimedherein, and, as it is fully described in the previously mentioned parentapplication, no further description of it will be given here.

WVhile the form of mechanism herein shown and described is admirablyadapted to fulfill the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the one form orembodi-' ment herein disclosed, for it is susceptible of embodiment invarious forms all coming within the scope of the claims which follow.
